@catherinesc88 If you read above, I explained that CS ABET accreditation does not really matter. It’s not used as a standard like it is for engineering. Some of the top CS programs are not ABET accredited, usually not because of a lack of CS requirements but of degree requirements in other areas such as hard sciences, which are not needed for CS like they are for engineering. For engineering, your advisor is right. CS is the awkward intersection of math, engineering, and science, and thus often has classification issues. This is usually best remedied by separating CS into its own college/area along with related fields like data science, information science, cybersecurity, etc as many schools are starting to do.
Sorry to scare, my verbiage could have been a bit more clear to be safe
